Results at gauss/integration points. Please help. Urgent!
(OP)
Hello,
Is it possible to get the results at the gauss/integration points directly, instead of the results at nodes or elements (which are interpolation of results at a few gauss points).
I need to know this urgently. Thank you very much.

yes, it is:
ERESX,NO
directly copies the gaussian (integration) points results to the nodes, without extrapolation through element shape functions.

This command should be used before solving the problem and I have already solved the problem.
And I want to know some method where I can directly see the results at the gauss points, not the nodes or elements.

I can't get you on the ERNORM thing. Can you please explain.

Actually, my guide works with another software ABAQUS, where we can get the results at the gauss points. As the results at gauss points are the direct results of solution, she insists to see the results of my calculation at the guass points too.
If you could help me!

yes I can understand the point, but as Stringmaker says I don't see why you couldn't "reverse" the problem to a more "readable" fashion and express everything as nodal results... Bear in mind that what you "see" in post-processing are elements / nodes, never gaussian points, so the stress field you would see even with ERESX,NO would be artificial (copy of values betwen non-coincident locations... in my opinion, much more misleading as the extrapolation using the elem shape functions!).
However, ERNORM works in /POST1, while ERESX works only in /PREP7 or /SOLU. If the solution doesn't take weeks to complete, you'd better re-run with ERESX,NO...

If all she is concerned with is convergence than as the others say ENORM should do the trick.
RE: Results at gauss/integration points. Please help. Urgent!
Could you also please tell me, for the mesh convergence check using ENORM, what value of structural error energy and absolute maximum stress variation can be taken as acceptable results.
For example in my case,
The absolute stress variation is between 0.3 and 36
And, the structural error energy is between 1e-08 to 0.4e-04.
Thanks. :)
